Answer to Question 1

A, B, D
The reduction in temperature creates positive physiological and biological effects, such as pain relief, reduction in muscle spasm, decreased nerve conduction velocity, and decreased inflammation edema, caused by constriction of blood vessels.

Answer to Question 2

B
Immerse the strip briefly in the urine sample, and then remove it and tap it gently on the side of the container; prolonged exposure to excess urine can dilute reagents. Stagnant urine stored in the bladder overnight or for long periods does not reveal quantities of glucose and ketones excreted by the kidney at the time of testing. Kits that contain tablets do not also use strips; the tablet contains the reagent and changes color to indicate chemical properties of the urine. Tap the strip gently against the side of the container to shed excess urine; do not wipe it.
